The selection circuit 13 in the control selection circuit 7 and in the main control selection circuit 12 are identical in structure and shown in S ¹ Ig, 7.

The second input of the third AND-gate 38 is with the buffer memory 32 and the output with the final report line 19 connected.

the effect of the control system is explained in more detail below described.

The system begins to work after actuation of the starting device 17.

This operation could e.g. B. also switch on the power supply The start signal controls the selection circuit 13 in the main control selection circuit 12, which is located at the top of the system structure, in the upper control level. This then activates the preferred line 15, which in turn the selection circuit 13 in the control selection circuit 7, in the next lower control level, controls · This process is repeated until a process sub-control system 8 is achieved in a control subsystem 6, which is activated and takes over the process control Via puncture control buttons in the input device 4- can then another control subsystem 6 can be selected. When a function key is actuated, the input device 4 sends out a keyboard code which is transmitted via the! Pastature code bus 3

the control subsystem 6 that has just been activated is reached. If the keyboard code is made up of eight bits, for example for example the more significant four bits for addressing the control level and the lower four bits are used to address the priority line 15 or one of the activation lines 14.

the keyboard code for the first shark is analyzed in the first code control circuit 9 of the control subsystem 6. There are two possible variants:

Version 1:

The keyboard code does not have an address of a higher control level. The code control circuit 9 gives the keyboard code directly via the intermediate control code bus 16 to the process sub-control system 8, which then triggers the corresponding control activities to control a sub-process 5

Variant 2:

The keyboard code has the address of a higher control level. In this case, the code control circuit 9 activates the process sub-control system 8 via the final treatment line 18. The process control 8 then carries out all activities "Forwarding of the keyboard code.

When these activities are finished, they are activated via the Final completion report line 19 the code control circuit 9. This then reports the received keyboard code to the control selection circuit 7 via the first control code bus 10 in the next higher control level, the keyboard code reaches the code control circuit 9 in the Control selection circuit 7, where again two variants are to be distinguished.

The keyboard code does not have an address of a higher control level, but an address in which the control selection circuit 7 is located.
In this]? All, the keyboard code is sent via the 2-way code bus

16 reported to the selection circuit 13 and the selection circuit takes over activities for controlling that process sub-control system, for which the keyboard code is intended.

The lastatureode bears the address of an even higher one, in the example the upper control level.

In this EaIl the keyboard code is again as already described, from the Oode control circuit 9 via the selection circuit 13 back to the Oode control circuit 9 and from there to the second Control e-bus 11 to main control selection circuit 12 in FIG the next higher control level, d. H. the above, reported and processed.

Each of the rough description of the mode of action is now the Control process described in detail.

! Whenever a new keyboard code is available via the keyboard code bus 3, this is in the first decoder circuit 23 of the code control circuit 9 of a control subsystem 6 (! Ig. 5) evaluated, d. That is, it is checked whether it is for the lower or higher control level is determined.

! alls the keyboard code is not intended for the higher control level is, the ^ ndbehandlungsleitung 18 remains inactive and the first gate circuit 21 gets via the first Eegator 24 on active signal, with which the attached keyboard code via the intermediate tax code bus 16 for general control 27 of the process sub-control system 8 (,! Ig. 6) is switched through directly. The general control 27 now takes over the control of sub-process 5 according to the content of the keyboard code.

! alls the new keyboard code is intended for a higher control level is, the ignition treatment line 18 is activated, whereby the first gate circuit 21 is blocked via the first inverter 24. At the same time, the second sequence control 26, the z. ü. a stepping mechanism can be set in motion in order to set the defined basic state to the partial process 5, after that is done, the final completion line becomes

19 activated and the second gate circuit 22 opened, whereby the new keyboard code reaches the next higher control selection circuit 7, which then carries out the further evaluation. The first AND gate 28 has the task of starting the second sequence control 26 in the process sub-control system 8, which is not controlled by an active signal on the preferred or activation line 15 »14. The second AND gate 29 prevents the process part control system 8 can issue a final report that is not controlled by an activated activation line 14, what otherwise confuse the forwarding of the current keyboard code to the correct control selection circuit 7 would.

This evaluation takes place again in the code control circuit 9 of the control selection circuit 7 in an analogous manner, that is, if the keyboard code is not intended for a higher control level, the final treatment line 18 remains inactive and if the keyboard code is intended for a higher control level, the bundle treatment line 18 activated. When the final treatment line 18 is inactive, an active signal is sent to the first gate circuit 21 of the Oode control circuit 9 of the control selection circuit 7 via the first cone 24, with which the applied keyboard code is switched through directly via the intermediate control electrode 16 to the second DeeOder circuit 33 of the selection circuit 13 (Fig. 7). If a new keyboard code is present, it is transferred to the buffer memory 32, passed on to the third decoder circuit 36 and a new preferred or activation line 15 »14 is thus switched on.

When the final treatment line 18 is active, the buffer memory is reset and the code is sent to the third decoder circuit 36 to switch off all priority and activation lines 15 » issued.

After this is done, the completion report line 19 becomes activated and the second gate circuit 22 of the code control circuit 9 of the control selection circuit 7 opened, whereby the new keyboard code to the upper control level, d. H. to the main

-χ-

^ / 7

Control selection circuit 12 arrives, which then takes over the further evaluation.

in the main control selection circuit 12, the processing is carried out of the transferred from the control option 7 'Keyboard codes through the control circuit 9 and the selection circuit 13 in the manner and manner already described, d. H", when the intermediate control code bus 16 is between the override control circuit 9 and the selection circuit 13 of the main control selection circuit 12 from the signalless to the signal-carrying state passes, this is done by the second decoder circuit 33 recognized and the pending new keypad code in the buffer memory 32 taken over, passed to the third decoder circuit 36 and thus a new preferred or activation line 15 »14 switched on.

In the event that by inputting a signal from the starting device 17 shows the line between starting device 17 and selection circuit 13 of main control selection circuit 12 in FIG passes the active state, the monoflop 34 sends a set pulse to the buffer memory 32 via a set line, that this outputs the code for setting the preferred line 15 to the third encoder circuit 36.

Jim beginning of the third decoder circuit 36 of the selection circuit 13 of the main control selection circuit 12 is now one of the starting device 17 or initiated by the god control circuit 9 Signal state before, which is now via the preferred or activation line 15; 14 to the selection circuit 13 of the next lower Control selection circuit is passed. The signal shift in the selection circuit 13 of the control selection circuit 7 takes place analogously, so that at the output of the third decoder circuit 36 of the selection circuit 13 of the control selection circuit 7 either from the starting device 17 or from the god control circuit 9 of the main control selection circuit 12 or from the code control circuit 9 of the control selection circuit 7 initiated signal state before the now over the preferred or activation line 15; 14 to a process control system 8 of a control subsystem 6 is transferred.

If the preferential and activation line 15; 14 in the active State is transferred, the first sequence control 25 is set in motion.

The first sequencer 25, the z. B. stepping mechanism can be, has the task of the sub-processes 5 in the special To transfer output control state After this is achieved, the connection line between First sequence control and general control activated and thus the general control 27 takes over the Control of the sub-processes 5 "and thus those assigned to it special circuit functions

A special application of the process sub-control system 8 (, Fig. 6) is present when the task of general control 27 consists in the fact that, after the work of the first sequence control 25 has been completed, it is sent to the input device via the output data bus 2 4 has to issue the control command that this sends out a certain new control code and thus Force the connection of a new control subsystem 6. The control subsystem designed in this way would then, as it were, be an automatic system with a precisely defined control sequence without additional necessary operator actions. Finally, it would transfer the process control to a control subsystem 6, in which the usual context would exist again that as a result of an operator action from the process or from the input device 4, only a certain activity is triggered. The next activity would then be triggered first require a new operator action or feedback.

in Fig. 8 is the functional diagram of a practical application of the control system in a remote ink zone adjustment shown on printing machines.

The sub-processes 5 are in this case by the known elements, like the servomotors for the ink fountain screws and the Potentiometer for the position feedback of the individual ink zone screws as well as embodied by an order store. In the first main operating mode "continuous printing", the control selection circuit would be 7.1 select one of the control subsystems 6, which in this case use the known functions

Realize position "," group adjustment "and" total adjustment ". The arrows indicate the! Punctures that go through the Control selection circuits 7 can be selected with the aid of preferential lines 15 or via activation lines 14.

In the main operating mode "I? Ortdruck" the above-mentioned. üHinctions realized in i? orm of sub-modes in the known manner.

In the second main operating mode, "set-up" by means of the control selection circuit 7.2 these functions were carried out with the aid of the Job memory only simulated.

If the sub-mode "Transfer to the machine ^{1" is selected} , the position values simulated and thus stored in the memory 20, for example at the start of a new print job prepared by the simulation, would be converted into real setting values in the printing machine.

This would include an automatic control sequence as described in the description the special application of the process part control system 8 was explained, required.

Subsequent to this automatic control sequence, a control command would then be sent to the input device 4, expediently the main operating mode "! ortdruck" and thus also finally the sub-mode "group adjustment" selected, the is most often needed in the printing process.

The advantage of the control system described is that that in the case of a control problem with several, mutually independent j? nction complexes (operating modes; a control in a simple manner from one operating mode to another possible is.

There is also the possibility of converting these operating modes into higher-level main operating modes and according to their order of priority to subdivide sub-operating modes, whereby the presented structure can also be expanded as required.
